On all complete assembly packages, it is very possible that the valve springs are not correct for your camshaft. All valve springs should be checked for compatibility to your camshaft. Severe wear of valve train components and severe engine damage could result from failure to do this. Check spring requirements before heads are installed on the engine. If in doubt please contact your camshaft manufacturer or USA Performance Parts. We do carry optional springs for all of your needs.
